ASP.NET Core 10 quietly held three routing styles at once (Minimal APIs, FastEndpoints, Carter), and Aspire (GA Nov 2024) brought the .NET ecosystem its first serious cloud-native orchestration. UI fractured into three lanes — Blazor United (Server + WASM + SSR + streaming), .NET MAUI, and the community-beloved Avalonia 11. We cover EF Core 9, MediatR, MassTransit, NServiceBus, NativeAOT, Roslyn analyzers, NuGet, the dotnet CLI — and Korean / Japanese real-world adoption.

ASP.NET Core 10은 Minimal APIs / FastEndpoints / Carter라는 세 가지 라우팅 스타일을 동시에 품었고, Aspire (2024년 11월 GA)는 .NET 진영 최초의 본격적인 클라우드 네이티브 오케스트레이션을 가져왔다. UI 쪽은 Blazor United (Server + WASM + SSR + streaming)와 .NET MAUI, 그리고 커뮤니티의 사랑을 받는 Avalonia 11이 셋으로 갈라졌다. EF Core 9, MediatR, MassTransit, NServiceBus, NativeAOT, Roslyn analyzers, NuGet, dotnet CLI — 그리고 한국·일본의 실제 채택 사례까지 정리한다.
